Degra

Degra is a prominent Xindi-Primate scientist who represented his people on the Xindi Council.

He is a humanoid Xindi, one of the five sentient species originated on Xindus, a planet in the Delphic Expanse which would be destroyed around the 20th century. In their effort to find a new home, the Xindi were told by a time-travelling species (known as the Sphere Builders) that their future planet would be destroyed by the Federation.

Degra was tasked with building a weapon capable of destroying Earth. While his prototype was a success, Degra was convinced by Captain Jonathan Archer that the Sphere Builders were lying: after that, Degra helped in preventing the destruction of Earth.
